GridView. Get value.

[shapper]

Hello,

I need to get the value of a Gridfiew field named "Channel" which is
the first column of the Gridview.

I want to use that value to build the ToolTip of an image. How can I do
this?

Here is my code:

Private Sub gvRSSChannels_RowDataBound(ByVal src As Object, ByVal e
As GridViewRowEventArgs) Handles gvRSSChannels.RowDataBound

' Bind row elements
If e.Row.RowType = DataControlRowType.DataRow Then

' Define row view
Dim rvRSSChannels As DataRowView = CType(e.Row.DataItem,
DataRowView)

' Define channel data column
Dim channel As String = rvRSSChannels("Channel").ToString

' Define cells collection
Dim tccRSSChannels As TableCellCollection = e.Row.Cells

' Define hfIcon hyperlink
Dim hfIcon As HyperLink =
CType(tccRSSChannels(tccRSSChannels.Count - 3).Controls(0), HyperLink)
hfIcon.ImageUrl =
Me.GetLocalResourceObject("hfIcon.ImageUrl").ToString()
hfIcon.ToolTip = Me.GetGlobalResourceObject("RSS", "{0}_Title")
' ******
End If

End Sub

See, where I have *****: "{0}_Title"
I thought {0} would work but it is not working.

Could somebody tell me why?

Thanks,
Miguel

Hi,

But why not do this in RowDataBound?
If I set there my ImageUrl can't I access the value of column 0 and use
it to create the tooltip?

Thanks,
Miguel
